Abstract: 1,250,286. Controlling temperature electrically. SUMITOMO METAL INDUSTRIES Ltd. and HITACHI Ltd. Jan.29, 1970 [Feb. 12, 1969], No.4441/70. Heading G3R. In a hot metal strip mill the strip 1 Fig. 1 (e. g. steel) after leaving rollers 2 passes through cooling water spray banks 1 to 6 and a control system (utilizing predictive and feedback control) including a computer determines the cooling power required to equate a detected temperature Tc at the output end of the cooler to a desired value reference Tco and controls the spray valves accordingly. The computer 10 (Fig. 5) receives as inputs - predicted values of input end temperature Tf and strip velocity V 2 , a setting value h of strip thickness, the reference value Tco of output and temperature also detected values of input and output end temperatures Tf 1  and Tc 1  and strip velocity V 1 . Computations are performed periodically on the receipt by the computer 10 of a pulse from a pulse producer 9 coupled to the velocity sensor and which produces a pulse each time the strip travels a unit distance #L. To offset delay in opening the valves the computer performs a first (pre-set) computation on the basis of the said predicted values until the leading end of the strip reaches the input end of the spray bank No. 1, the strip position being sensed by the temperature sensor - with respect to the remaining length of the strip, a second (control) computation is performed wherein the predicted values are corrected in accordance with detected values. Alternatively spray banks 1 to 5 may be operated on the basis of predicted values. (coarse control) while the finely adjustable spray bank 6 is controlled in accordance with detected values (fine control). A timer 11 coupled to the computer and pulse producer comprises a plurality of counters in known arrangement and each pre-set for controlling the spray valves successively from No. 1 to No. 6 in accordance with computed cooling powers. The valves are sized so that a succeeding one has greater cooling power than that of the preceding one. A mathematical explanation of the computations is given.

In a method of extracting sugar from bagasse by passing it through a diffusion trough 11 wherein it is subjected to the action of sprays 21 which are supplied with extraction liquid from containers 18 beneath the trough on the countercurrent principle, the trough comprises at least two zones including an entry zone 12, where thermal treatment is given to the bagasse by hot liquor sprays 33, and a diffusion zone 14, between which zones there is disposed a roller 23 which exerts a downwards force on the bagasse in excess of its own weight. Preferably the peripheral speed of the roller 23 is faster than the speed of movement of the bagasse in the diffusion zone. In the embodiment of Fig.1, the floor of the inlet zone is formed by a conveyer band 22 travelling at a speed faster than the peripheral speed of the roller 23 and an intermediate zone 13 is formed beneath the roller wherein the bagasse is supported either by a fixed plate 25 or by an endless plate conveyer (26), Fig.3 (not shown). The bagasse is conveyed in the diffusion zone by a succession of driven rollers 17a which are driven in batches by reciprocating mechanism consisting of cylinders 42 which are coupled through linkages and radial arms to freewheel devices at the individual rollers, the drive mechanism preferably being duplicated on the other side of the apparatus and out of phase so as to provide for a substantially continuous drive to the rollers 17a. In the spaces between the rollers 17a either small idler rollers 17b, or adjustable plates 49, or a combination of the two, are provided to prevent the bagasse falling between the rollers 17a. At the outlet end of the diffusion trough a compression roller 37 carried on pivoted arms 36 is provided, followed by a bladed wheel 38 to break up the bagasse as it is fed to a final press (not shown). The bagasse is supplied to the entry zone 12 by a shoot 29 which can be slewed about the axis of a vertical shaft 30, with its outer end running on an arcuate rail 31, to distribute the bagasse across the width of the trough. The trough is preferably of trapezoidal section, having inwardly and upwardly sloping sides to reduce the tendency of the bagasse to stick to these sides. In a modification, Fig.4 (not shown), only an entry zone and a diffusion zone are provided, the floor of the entry zone being formed by a conveyer band travelling more slowly than the bagasse in the diffusion zone, so that the bagasse builds up to a greater depth in the entry zone to provide a maceration stage following the thermal treatment.

Abstract: 1258007 Super-conductors SIEMENS AG 3 April 1969 [4 April 1968] 17671/69 Headings H1A A5 and A4D A super-conductor current carrier comprises a load conductor of a Type I of II super-conductor stabilized with a layer of a type III super-conductor. The materials are defined by their magnetization curves which in type I materials falls abruptly to zero at a critical field strength, in Type II materials has a faily sharp bend at a critical field strength and falls gradually to zero and in Type III materials has a relatively level maximum after the initial linear rise common to all super-conductors, and falls to zero more slowly than in the Type II materials. Examples of these materials are Type I Pb, Type II Nb, and Type III Nb-Zr, Nb-Ti and Nb 3  Sn. The composite conductor is especially suitable for A.C. power applications since the Type I or II load conductor exhibits low hysteresis loss. As shown, a Cu or A1 tube 3 or core is coated with a stabilizing layer 2 of a Type III superconductor such as Tc, Nb-Ti, Nb-Zr or Nb-Sn which is coated with a load conductor layer 1 of a Type I or II super-conductor such as pure Pb or Nb. The layers may be deposited by decomposition of appropriate halogens in hydrogen, e.g. Nb and Sn layers may be deposited to produce Nb 3 Sn. Alternatively the outer layer 1 of Type I or II super-conductor may be applied electrolytically or by plasma spraying. More than one stabilizing layer may be provided the materials being graded so that their critical field strengths for A.C. increase from the load conductor to the normal metal.
